Definitions
- the present invention relates to a tape guide structure for use in a video cassette recorder ("VCR"); and, more particularly, to a tape guide structure capable of allowing the tape in a tape cassette to be correctly loaded even if the tape is loosend.
- VCR video cassette recorder
- the tape cassette Ca when a tape cassette Ca is loaded in a VCR, the tape is normally located between a guide post 28 and a capstan shaft 26, as presented by the solid line L1 in FIG. 1.
- the tape is, then, drawn toward and wrapped around a head drum by a pair of pole bases 23, 24 moving along a pair of guide slots 21, 22, respectively.
- the cassette Ca upon the loading of the tape cassette Ca into the VCR, the cassette Ca first moves in a horizontal direction and, then, moves down in a vertical direction along loading slots 12, 13. Therefore, if the tape T is loosened to the extent that it passes over the central axis C of the guide post 28, the tape comes to be mislocated over the guide post 28 as presented by the projection line L2 in FIG. 1, resulting in malfunction of the VCR.
- a tape guide structure for use in a VCR into which a tape cassette is loaded, the tape guide structure comprising: a guide post provided with an upper cylindrical portion and a lower cylindrical portion with a diameter greater than that of the upper portion, the guide post being fixed to a deck; and a post cap provided with a head portion with a slant surface, the post cap being fixed on top of the guide post, thereby, when the tape cassette is loaded into the VCR with the tape loosened and contacting the slant surface of the head portion, allowing the tape to be loaded into a correct position.
- FIG. 1 depicts a schematic top view of a VCR, showing a state of a tape cassette loaded in the VCR;
- FIGS. 2A and 2B represent schematic side views of the VCR, showing a loading process of the tape cassette.
- FIG. 3 illustrates an exploded perspective view of a tape guide structure of the present invention
- FIG. 4 sets forth a schematic partial side view of the VCR, showing how the tape guide structure of the present invention functions.
- FIG. 1 will be from time to time referenced in describing the present invention. Furthermore, like reference numerals represent same components in the drawings.
- FIG. 3 a schematic exploded perspective view of a tape guide structure in accordance with a preferred embodiment of the present invention.
- the tape guide structure of the present invention comprises a guide post 30 and a post cap 40.
- the guide post 30 is provided with an upper cylindrical portion 35 and a lower cylindrical portion 31 with a diameter greater than that of the upper portion 35.
- the upper portion 35 contacts and guides the tape running in the VCR.
- the upper portion 35 has a protuberance 36 formed on top thereof and the lower portion 31 has a circumferential groove 34 formed therearound.
- the guide post 30 is fixed at a position adjacent to a capstan shaft 26 on a deck 10 (see FIG. 1).
- the post cap 40 is provided with a head portion 47 with a slant surface 49 for guiding a loosened tape into a correct position and a cavity 48 adapted to fit onto the protuberance 36 of the upper portion 35.
- the post cap 40 is also provided with a C-shaped claw 43 adapted to fit into the groove 34 of the lower portion 31 and a support body 41.
- the claw 43 and the head portion 47 are connected to each other through a connection portion 42.
- the support body 41 downwardly extends from a rear side of the claw 43, being fixed to the deck 10, thereby preventing the post cap 40 from rotating around the guide post 30.
- a plurality of notches 46a may be formed, at positions near the connection portion 42, on the inner surface of the claw 43.
